Why is there no signal on the phone when I make a phone call?

If your mobile phone can't make calls, you can use the following methods:

1. You can't make phone calls in certain scenarios.

(1) Unable to dial someone's number, indicating that the user is busy.

Maybe the other party has blacklisted your number. I suggest you try to contact the other party in other ways, and you can dial normally after removing the blacklist.

(2) The short number cannot be dialed, and the prompt number does not exist.

It may be that the cornet is beyond the specified use area. The cornet is for local use only. If the cornet cannot be used outside the designated area, it is recommended to dial ordinary 1 1 digits.

2. You can't make a phone call unless it's a specific scene.

(1) Please confirm that the mobile phone card signal is normal.

When the status bar of the mobile phone shows emergency call only or "×" symbol, it will lead to the inability to make a call.

Warm reminder: If the mobile phone card signal is normal, you can't make a call, and you will be prompted that the number is empty or turned off. Generally, it is a network problem of local operators. I suggest you contact the local operator.

(2) Please ensure that call barring business is not opened.

Some operators' calling cards have call barring service. If your calling card restricts outgoing calls, some or all calls will be restricted. Please consult the operator's customer service for details.

(3) Please enable the VoLTE function.

It is possible that the 2/3G call network environment in your location is not good, so I suggest you try to turn on the VoLTE function. When the VoLTE function is turned on, the HD icon will be displayed in the signal bar.

If your mobile phone card doesn't have the VoLTE function, or your mobile phone doesn't support the operator's VoLTE function, please pay attention to whether the status bar of your mobile phone can be switched to 2G or 3G normally when dialing. If you can't switch, it may be caused by insufficient coverage of 2G/3G networks in this area. I suggest you try calling from another place.

(4) Please restore the network settings.

It is recommended that you search in Settings to restore network settings and try to restore network settings.

Tips: Restoring the network settings will delete the WLAN and Bluetooth connection records, and you need to enter the screen lock password for verification.

If your mobile phone still can't make a call, I suggest you contact Huawei's customer service hotline (950800), or back up the information in advance (third-party applications such as QQ and WeChat need to be backed up separately), and bring relevant purchase vouchers to the nearby Huawei customer service center for testing.
